IMPROVEMENT IN ELECTRICAL BlLLlARD-REGISTERS.

Specification forming part of Letters Patent No. 164,66 l dated Jane Q2, 1575; application filed June 20, 1873.

To all whom it may concern:

Be it known that we, CHARLES HENRY RUSSELL and J ULIUS SAX, both ot' London, England, have'inven ted certain Improvements in Billiard-Registers, of which the following is a specification:

This invention relates to that class ot' billiard-registers in which electricity is employed to' actuate the indicating-machinery; and it consists, mainly, rst, in the combination ot' armatures carrying driving levers or pushes, with certain independent gea-ring and the indica-t.- ing-pointers; second, in the combination of certain mechanism for indicating the points made in the game, with certain mechanism for recording the number of games; it consists, further, in certain specific details of construction, which, in connection with the foregoing, will be fully described hereinafter.

A represents a dial, adaptedl by suitable divisions and numbers, to indicate, in connection with theindex-hands, the points made in a game. A1A2 represent dials, adapted to record the number of games played. a al represent the pointers, marked in a suitable manner to distinguish them from each other, 'and to identify one of them with each ball. a2 represents the shaft of the pointer or index-hand a, which, extending behind the dial into a suitable case or box, is held in proper bearings and provided with a gear-wheel, a, as shown. a3 represents a sleeve or cylinder inclosing shaft a, and carrying the pointer al, which is provide with a similar gear-wheel, a5, as shown. B B represent electric magnetic coils, attached to a battery, (not shown,) and b b, main wires, extending to certain actuatingknobs in the frame of the billiard-table, and bz a return wire for completing the circuit. C C represent armatures, pivoted at the lower ends to the baseplate of the case, and each provided above with a driving lever or pusher, c, the moving end of which is adapted to engage with the teeth ofthe gear-wheel a or a5, and give motion thereto. 'c' c represent springs, by means of which a proper returnmovement is given to the armatures. D D represent bars, each of which is pivoted at one end to a proper supporting-arm, and provided with a stud or stop, d, adapted in position and form to engage with the teeth ot gear-wheel e4 or a5, and to prevent any bacluvard movement ot' the same. d represents aset-screw, held in the bent end of the barl), which is adapted, by adjustment, to determine the limit ot' the rearward movement 0l" the armaturelever. d2 represents a set-screw, located above the gear-whcclsa4 a5, and provided with a beveled end, which is adapted, by adjustment, to determine the limit ot` the forward movement ot' the armature-lever. E represents a weight, connected with the shaftot'each pointer, which is adapted to keep them fixed in any position in which they may be moved.

rlhe foregoing description relates 'to themedium for indicating the points made in asingle game, and its operation is substantially as follows:

\`\"hen any one of the. players at the table depresses the knob identified with his ball, the electrical circuit is made complete, and coliseqnentlytheconnected magnet-is attracted byits armature, and actnates, by means ot' its pusher or driving-lever, the gear-wheel attached to theshai't. ot' the proper pointer, which latter is, of course, consequent-ly moved upon the dial.

The operation of each lla-lt ot' the app; is the same, one being identitied with the plain ball, and the other with the spot-ball.

For the purposeot' indicating the number ot' gaines played, the following mechanism is employed:

M represents a pinion, loose upon the main shaft, which is provided at each end with a disk, m, as shown. 'm1 ml represent pivoted stops, located upon the outer faces of thedisks m, which is provided with an inclined portion, m2, and a horizontal arm, m3, as shown. m* represents a spring, adapted to bear upon the horizontal arm mi* of the stop, and hold the same in place. N represents a stud, attached directly or indirectly to the gear-wheel of the indexhand, which is provided upon each side with an inclined tace, and adapted in position and size to collie in contact, in its revolution, with the stops m1, and give them revolution. O represents a gearwvlieel, engaging with pinion M, the shaft of which is provided, also,

with a pinion, o, engaging wit-h a gear-wheel, P, the shaft of which carries an index-hand in front of a small recording-dial, as shown.

By means of a pinion,p, and gearwheels R R S, the revolutions of the index-hand of the iirst recordingdial are recordedupon a second, and, if desired, they may be indicated, also, upon a third.

The operation of the game-recording mechanism is as follows: At every complete revolution of either point-er the disk M at once revolves, and this revolution, by means of the intermediategearing and pinions, causes the recording index-hand to move but one space, the gearing being arranged to reduce or diminish the movement in the manner well understood. l

As the pointers and their attached gearwheels are moved independently of each other, it will sometimes occur that the movement of one will force the stop of the opposite disk past the stud attached to the gearin g of the pointer, which is stationary. This result is accomplished without injury, as the stop is adapted to pass on the inside face of the stud wfhen moving backward against it, by means o it.

The construction described is quite simple, and yet effective for the purpose designed.

Having thus fully described our invention, what we claim as new, and desire t0 secure by Letters Patent, is

1. The combination of the armaturelevers C C, the intermediate gearing a a5, and the index-hands, substantially as described.

2. The combination of the armature-levers, theintermediate gearing, and the index-hands, with the game-recording mechanism, consisting, essentially, of the loose pulley M with its disks and stops, the intermediate gearing', and the recording dial and index, as described.

3. The combination of the pusher-lever C, and the stop d1 for limiting its backward movement, as described.

4. The combination of the pusher-lever C, and the stop dz for limiting its forward movement, substantially as described.

5. The combination of the pusher-lever C, and the stops d* d2 for limiting its forward and backward movement.

G. The combination of the index-hands al az, and the gearing a a5, having the weight E, as described.

7. The combination of the studs N, the

spring-stops ml, the loose pinion M, and the connecting-gearing, as described.
